APPARATUS FOR SURFACING BRICKS AND TILES.

Application led June 11, 1915.

To all whom t may concern.'

Be it known that I, CHARLES C. VVOLPE., a citizen of the United States,residing at I-Iaydenville, I-Iocking county, Ohio, have invented a newand useful Improvement in Apparatus for Surfacing Bricks and Tiles, ofwhich the following is 'a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a side elevation of apparatusembodying my invention;

Fig. 2 is a plan View of the same;

Fig. 3 is a view on a larger scale; and

Fig. 4L is a bottom plan view also on a larger scale of one of therotary surfacing members.

My invention has relation to apparatus for imparting a roughened surfaceto tiles,

bricks and other structural shapes of terra cotta and clay, the surfaceimparted being what is commonly designated in the trade as a texsurface.

The Object of my invention is to provide apparatus which can be readilyused in connection with the usual forming dies and which will impart thedesired surface to the -clay bar or shape as it issues from the saiddie. A further objectof the invention is to provide means of thischaracter which can be operated with very little, if any, additionalpower or expense.

Referring to the accompanying drawings, in which I have sh-own thepreferred form of my invention andwhich will now be described, thenumeral 2 designates the usual forming die of a brick or tile machine. 3designates a suitable guideway which is placed in advance of the orificeof the die and in line therewith and is adapted to guide the bar 4L ofclay (indicated in dotted lines) as it issues from the die. 5 designatesrotary members which are provided at their lower sides with a pluralityof pins or teeth 8. vided with spindles or shafts 6, which are free torotate in bearings 7 on the guide 3. The spindles are movably mountedwithin the bearings, so that the rotary members 5 are free to moveupwardly, s-o that the depth of the cuts in the clay bar made by thepins or teeth are determined by the weight of the rotary members. Ipreferably employ at Specification of Letters Patent.

These rotary members are prof Patented Mar. 2"?, 191?. seria1'No.3a,A7o.4 I

least two of the members 5, one at each side of the guide 3, andpartially overhanging the guideway, so that as the bar of clay7 travelsto the guideway, the members 5 will be rotated by contact of the claywith the pins 8. The two members 5 being located at opposite sides ofthe guideway will be rotated iuthis manner in opposite directions,thereby scratching and re-scratching the upper surface of the clay barand producing a complete roughing of such surface.

The numeral 9 designates a roller, preferably having a resilient ortextile surface portion, and which is j ournaled transversely of theguideway beyond the scratching members 5. The purpose of this roller isto roll down the loose material left by the scratchers and to producewhat is known as the tex surface.

It will be noted that no belts, pulleys or other means of transmittingpower to the scratchers or rollers is required, the movement of thesebeing effected by contact with the moving bar or column of clay. Thedevice is extremely simple and effective in its 4operation and enables atex surface to be produced with little, if any, additional labor orexpense.

I do not desire to limit myself tothe particular embodiments of myinvention which I have herein shown and described, since it is obviousthat the guideway may be of any suitable construction, that more thantwo of the rotating scratchers may be employed, if desired, and variousother changes may be made within the spirit of the appended claims.

I claim:

l. Apparatus Of the character described, co-mprising a rotary memberhaving a plurality'of scratching points and located in advance of theexpressing die of a clay working machine, said member being free to berotated solely by the contact of its scratching points with the movingclay column, substantially as described.

2. Apparatus of the character described, comprising a guideway for themoving bar or column of clay, and rotary members overhanging theguideway from opposite sides and having each a plurality of dependingscratching points or pins, said members being free to be rotated solelyby the contact of said ,points or pins With the moving column of clay,and the two members having their centers of rotation at opposite sidesof said guidevvay so as to be rotated in reverse directions,substantially as described.

3. Apparatus of the character described, comprising a guideway for themoving bar or column of clay, and rotary members overhanging theguideway from opposite sides and having each a plurality of dependingscratching points or pins, said members 'being free to be rotated solelyby the contact of said points or pins with the moving column of clay,and the two members having their centers of rotation at opposite sidesof said guideway so as to be rotated in reverse directions, togetherwith a surface roller journaled transversely of the guide- Way beyondsaid rotary members and having its surface adapted for contact with thesurface of the clay column, substantially as described.

Ll. Apparatus of the character described, comprising a rotary memberhaving a plurality of scratching points and located in advance of theexpressing die of a clay Working machine, a bearing, a stem connected tosaid rotary member mounted Within the bearing and adapted to be freelymoved therein, said member being free to be rotated solely by thecontact of its scratching points with the moving clay column;substantially as described.

In testimony whereof, I have hereunto set, my hand.
